Well... I was a big, big fan of the Portland Trail Blazers in the late 90's and early 00's until their image went completely downhill... It's not that the team started losing, I can live through a losing team. The image was just terrible and the team fired Mike Dunleavy, IMO by far the worst move the franchise has ever made and one of the worst franchise moves in the history of the NBA. Yes, I say this knowing full well my team passed over Michael Jordan in the draft (NOT a mistake, by the way).
Since then I started following the Mavericks... I'm a DFW native so went with the original home team. But living about 10 blocks away from the Rose Garden, I would like to see the Blazers pick the pieces back up. Until then, I just can't bring myself to root for them.
